'7 claims.

The present relates to vacuum cleaners and more particularly to a new and improved type of motor support therefor. The present applicationl which permits ready assembly or removal ofA the motor and fan unit from the vacuum cleaner casing.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements,

Aand arrangement of parts which will be exemplied in the construction hereafter set forth and the scope of the application of which will besindicated in the appended claims.

In the accompanying drawings:

(Cl. ZBO-117) casing, there is further provided a cap 28 which encloses the conical portion 24 of the casing and is secured as by bolts 30 to the annular flange 22. The details of the aforementioned structure are all fully disclosed in the above-mentioned. application, and no further reference will be made to them except when necessary to an-understanding of the invention herein. In accordance with the present invention, the motor mounting, which is generally designated as 32, comprises a bushing 34 and a spider 36 extending outwardlylfrom the bushing and securable to the vacuum cleaner casing. More particularly, the bushing 34 is made of rubber or any other resilient material and is provided with a central opening 38 whereby the bushing may be tightly fitted onto a bearing surface 40 ex- Vacuum cleaner utilizing a motor mounting of the type embodying the invention herein;

Fig. 2 is an end View partly in section of the motor mounting in its assembled position within the vacuum-cleaner unit; and

Fig. 3 is a perspective view of the motor mountl ing bushing and supporting spiders therefor.

Referring to the drawings, there is shown for purposes of illustration a vacuum cleaner of the portable tank type for which the motor mount` ing constituting the present invention is particularly adapted. The cleaner comprises generally a casing l0, runners Il for normally supporting Y the casing in a horizontal position, a vacuum creating u'nit including a motor I2, a rotary suction pump or exhaust fan I4, an air filter I6, `a supporting and sealing gasket I1, adust bag tending rearwardly from the housing 42 of the motor l2. The bushing is of cylindrical form, and its outer periphery has cut therein a groove 44 to provide spaced annular ribs 46.

Positioned within the groove '44 are a plurality of holding members 48, each including an arcuate portion 50 terminating at one end in a short radially extending securing lug 52 and at its other y end in a long spacing arm 574. In the embodiment illustrated, three holding members are provided; each extending through approximately 120, whereby the leg 52 of one holding member abuts the spacing arm of the next holding member, whereupon the two may be secured by a suitable screw 58 extending through aligned openings for receiving same. When so secured, the spacing members provide in eiect a complete circumferential holding ring or hub carrying the three radially extending spacing arms 54. Each spacing arm 54 in turn terminates in a laterally extending securing lug adapted to abut against the circumferential flange 26 carried on the rear end of the conical portion 24 of the casing l0. When properly aligned with the ange, the lug 60 may be secured thereto by suitable screws 624 'extending through aligned openings provided in the. members.

From the foregoing it'will be seen that each holding member may be readily stamped from any suitable metal and then quickly assembled onto the bushing 34 and, when so assembled, kept in proper position by the ribs 46 to each side of the groove 44. The holding members are so constructed that they may either be assembled into the completed spider and then mounted on the bushing by distorting same and then" snapping it intov the band-formed by the holding .members, or the sections may be assembled directly onto the bushing. Due to the fact that a resilient distortable bushing is used, the spider could, of course, be made of one piece. With the spider assembled on the bushing, the latter may be mounted on the bearing part of the motor by simply forcing it thereon. When 'so positioned, the bushing may be held in place by an end plate Il bearing against the end of the bushing and secured to the motor bearing 4portion by a screw 66. Upon insertion of the motor within the casing, the spider may be readily secured to the ilange 26 of the casing. To give further resiliency to the bushing, the body portion may also have a plurality of openings 68 cut therein in axial alignment with the bearing opening 38.

In the embodiment illustrated, the bushing 34 is also provided with a rearwardly extending peripheral ridge which cooperates with the circumferential ridge 46 to provide a shoulder support for one end of a screen illter 12, which lter has its forward end supported on acircumferential shoulder 'I4 extending rearwardly from the c ap member 28. u
